This invention relates to cracking and grinding machines, and is particularlyadapted to" the cracking .of filbejrts, walnuts," aggregates grains 'and so forth.

The primary object of 'the inventionis to provide a cracking and grinding machine that can be adjusted to crack nuts of any size in such a manner that the kernels of the nuts will be unharmed. H c

A'further object of the invention is the designing of a nut cracking and grinding machine hav- "inga large output capacity'in the cracking of the nuts.

A still further object of the invention is the designing of a cracking or grinding machine that is economical to build and having a minimum number of mechanical parts.

These and other incidental objects will be apparent in the drawings, specification and claims.

Referring to the drawings:

Figure 1 is a side elevation of our new and improved cracking and grinding machine.

Figure 2 is a plan view of Figure 1.

Figure 3 is a fragmentary end sectional view, taken on line 3-3 of Figure 1, parts broken away for convenience of illustration.

Figure 4 is a fragmentary end sectional view. taken on line 4-4 of Figure 1, parts broken away for convenience of illustration.

Figure 5 is an enlarged fragmentary sectional view, taken on line 5-5 of Figure 3, illustrating the method of cracking nuts.

Figure 6 is a still further enlarged fragmentary sectional view, taken on line 6-6 of Figure 3, illustrating the cracking of the nuts.

Figurefl is an enlarged fragmentary sectional view of one of the screws for adjusting the cracking plate.

Referring more specifically to the drawings:

Our new and improved nut cracking machine consists of a supporting framework I, having a horizontal shaft 2 journalled within bearings 3, the said bearings being mounted to the frame I. Keyed to one end of the shaft 2 is a cracker or grinding disk 4.

A cracking anvil 5 is vertically mounted to the upper framework 6 of the frame I by way of the cross member 1. The cross member 1 is adapted to slide on the frame 6 so that the anvil plate can be adjusted towards or away from the face of the cracking or grinding disk 4. The position of the anvil is determined by the adjustment of the threaded rods 8, two of which are pivotally afiixed to the bottom of the anvil [9, while one rod is pivotally affixed to the upper part of the anvil at H).

sciaims. (01-. 14 c- -11) Y Cross frame members I I and 1'2 are fixedly jsecured within the vertical frames l3. Internally threaded sleeves M are loosely and rotatably mounted within the said cross memberframes, as best illustrated in Figures 1 and 7. The. sleeves l4 have a flange 15 formed thereon adapted to contact one side of the cross frame on one side anclaremovable flange I6 adapted to engage the opposit side of the cross frames II and I2, positioning the sleeve relative to the said frames;

Hand wheels llform part ofthe sleeve l4, the

I "said" hand wheels adapted to rotate the sleeve adjust the rods 8 longitudinally thereof, thereby positioning the anvil 5 to the proper distance and angle to the cracking disk 4. The two lower sleeves M are geared together by the cross chain ['8 so that on turning the knob HA the bottom of the anvil will be moved away or towards the cracking disk in unison.

The adjustment of the upper threaded rod 8 by the hand wheel I! will adjust the position of the upper part of the anvil relative to its distance from the cracking disk. In the operation of the cracking machine the upper side of the anvil is spaced a greater distance from the cracking disk than the lower side. The nuts are cracked in a single layer on approximately a horizontal position relative to the center line of the cracking disk.

We will now describe the operation of our crackin machine. The nuts I9 enter the hopper 20, referring to Figures 3 and 5, falling down in single file to about the position indicated at 2| between the cracking disk 4 and the anvil 5. At this point the radial ribs 22 formed on the cracking disk strike the nuts against the anvil plate 5 cracking the same. These ribs extend a short distance from the face of the disk in order to accomplish the cracking operation, although in some instances the ribs may be dispensed with by roughening the face of the disk for gripping the side of the shell of the nut. The nuts are then delivered by way of the chute 23 from the machine on to a conveyor or other suitable receiving equipment.

The cracking disk 4 is revolved by the motor 24 by way of a suitable reduction gear as indicated at 25. The bottom 26 of the anvil, referring particularly to Figure 4, is located approximately in line with the center of the cracking disk 4. The angle to and distance away from the cracking disk is determined by the adjustment of the screws 8.

What we claim is:

1. A cracking and nut grinding machine, comprising a base, a power driven grinding disk mounted on the base, a series of radial ribs on one face of the disk, a flat anvil spaced from and opposite the face of the disk having the ribs, the width of the flat anvil being greater than the diameter of the disk and its lower edge terminating substantially on a line with the center of the disk, an inclined hopper above and to one side of the center of the, disk, the hopper having a bottom, the rear wall of the bottom of the hopper being inclined toward the face of the disk having the ribs to feed nuts to the space between the anvil and disk, one end wall of the hopper extending down in the space formed between the disk and the anvil and terminating substantially. in horizontal alignment with the center of the disk, a pair of upright bars mounted on the base, upper and lower cross bars secured to the upright bars, a pair of screws mounted in the lower cross bars, said screws being pivoted to the lower portion, of the anvil, a single screw mounted on the upper cross, bar, said single screw being pivoted to the upper portion of the anvil, adjustment of the screws determining the inclination and; spaced relation of the anvil to and from the face. of the disk having the ribs.

2. A structure, as defined in claim 1, wherein .means are provided for simultaneously adjusting on one face, a flat anvil mounted in acute angled spaced relation to the face of the disk having the ribs, the face of the anvil adjacent the disk being smooth, the bottom of the anvil terminating substantially in horizontal alignment with the center of the disk, a pair of screws pivoted to the lower portionv of the anvil, means for simultaneously adjusting said screws, a single screw pivoted to the upper central portion of the anvil, adjustment of the screws determining the angular position of and the spaced relation of the anvil to the disk.
